I have 2 questions for the history buffs among us. I have a '57 1/2 ton
stepside whose 6 cylinder was disassembled and allowed to rust up before I
purchased the truck. I removed a V8 from a 1957 Chevrolet
bus and put it in the truck. I did not have to do any work to the bus
motor, so I didn't have the heads off to measure things.
1. I believe that motor is a 265 or 283 but can not be sure. The number
on the block in front of the right hand cylinder head reads F4I7S. Does
anyone know what the displacement is from this number?
2 What year was the engine built?
I am hoping the engine is really a 1957 and that it was an option in the '57
stepside 1/2 ton. It would make me feel like my truck is more "authentic".
